FASTENING DEVICE FOR WINDOWS.

Specification of Letters Patent.

Patented March 2, 1909.

Application filed July 7, 1908. Serial No. 442,285.

To all whom it may concern:

Be it known that I, JAMEs L. iil'aLLoar, a citizen of the United States, residing at Evanston, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Fastening Devices for Windows, of which the following is a specification.

My invention relates to a fastening device for windows, and has for its object to provide, as a protection against burglary, a simple, inexpensive and easily operated sash-fastening device, by means of which the sashes of a window may be held locked in any desired position, either closed or partially opened.

The device consists essentially of a block, or similar member, which is provided with edges or parts that have a gripping engagement upon the sashes, and, if desired, upon the window frame also, when it is attempted to move either of the sashes in a direction to open or further open the sashes; the block being so constructed that it may be turned out of its engaging position when desired, so as to be ineffective.

The'invention, as embodied in certain preferred forms, is illustrated in the accompanying drawings, wherein-- Figure 1 is an elevation of a window, taken from the inside, illustrating the application of the device of my invention. Fig. 2 is a detailed elevation of one side of the window with parts in section. Fig. 3 is a sectional plan view on the line 33 of Fig. 2, looking in the direction of the arrows. Fig. 4 is a perspective view of the fastening device. Fig. 5 is an elevation, with parts in section, showing a modified form of device. Fig. 6-is a detailed elevation of a window showing a further modification. Fig. 7 is a sectional view on line 77 of Fig. 6 and Fig. 8 is a section through the device of Figs. 6 and 7.

Like characters of reference indicate like parts in the several figures of the drawings.

Referring first to Figs. 1 to l inclusive, A represents the lower sash of a window, B the upper sash, C, C the cords of the lower sash, for which, of course, chains may be substituted D the jamb on one side of the window and E the parting bead. These parts may be of any desired form and construction. F represents the fastening device of my invention. It is preferably a metal block and tion 9. The block F seats on the meeting i i is provided with a channel out of line with the normal position of the window cord, when the device is in operative position, '1 through which the window cord runs, so as to exert a constant pressure tending to force the device toward the corner between the stile of the upper sash and the j ainb D. This channel may consist of an oblique perforarail of the lower sash. Preferably it is provided with means by which its firm engagement with the lower sash is insured. For example, the under face of the block may be provided with the edges 10, 11 termii'iating in a point 12. The block is also provided with means for gripping or engaging or biting into either the upper sash or some part of the window frame, or preferably both the upper sash and the window frame. For example, the block may be constructed so as to have a projecting edge 13, which may be toothed as shown and which engages with the stile of the upper sash. The block may likewise be provided with the biting edge 14, which engages with the parting bead E, and with a similar edge 15, which will bite into the jamb D. I prefer that these edges should have tooth like formation, in order to take a firm grip on the wood, but such edges might not be necessary under all circumstances. So long as a firm grip is effected between the block and the sashes and window frame, when it is attempted to move one or the other of the sashes to open it, the object of my invention is attained.

The device may be applied on one side of a window or it may be applied on each side, as shown in Fig. 1. When the device is in the position shown in Fig. 2, whether the sashes be in closed position or whether one or the other be partly open, a movement of either sash in a direction to open the saineor further open it, as the case may be, will cause the fastening device to be ammed between the sashes and likewise against the window frame, effectually preventing tampering with the window. The window cord, because of the oblique position of the cl'iannel through which it passes in the block, tends to keep the block tilted over against the stile of the upper sash and against the window frame. The weight 011 the window cord keeps this pressure constant. When it is desired to open the window, all that is necessary is to turn the block around on the cord into the position shown in dotted lines in Fig. 3, where it will not interfere with the ordinary opening and closing of the sashes. In this position the perforatlon 9, as I prefer to construct the device, will be substantially in line with the normal osition of the window cord.

In Fig. 5 I have shown a modified form of device, in which the jamming action of block F is increased by means of a projecting tooth or spur 16 which extends into the slight space between the lower sash and the jamb. This form of device might be used on a window such as shown in the first three figures. t is particularly suitable, however, for a window in which the stile of the lower sash. has the projection 17 above the meeting rail, as shown in Fig. 5.

Figs. 6 to 8 inclusive illustrate another modification designed to be used upon windows having no sash cords or in which the sash cords are not exposed. The block F is provided with an oblique slot 18 at its lower and inner corner by means of which the block is swiveled on a screw 19, or other fastening device secured to the lower sash,

' the block being pinned to the screw by pin 20. Normally the block will be tilted toward the upper sash and the window frame, so that a lifting of the lower sash or a lowering movement of the upper sash will cause the block to jam in between the sashes and against the window frame. when the device is to be thrown out of action,-it may be merely tilted backward on the screw 19.

I do not limit myself to the particular forms and constructions above shown, as modifications may be devised which will come within the spirit of my invention. The device might be made of other material than metal. The gripping means on the block might be of different construction than shown.

I claim:

1 The combination with the frame, sashes and sash cord of a window, of a sash-fastening device adapted to be held in gripping engagement with one of said sashes and an adjacent part of the window frame, by means of said sash cord. 7

2. The combination with the frame, sashes and sash cord of a window, of a sash-fastening device adapted to engage with one of the sashes and an adjacent part of the window and having a channel through which the sash cord passes angularly positioned with respect to the normal position of the cord.

3. The combination with the frame, sashes and sash cord of a window, of a sash-fastening device having a channel through which the sash cord passes angularly positioned with respect to the normal posltion of the cord,

and having engaging edges which engage respectively the upper and lower sashes.

4. The combination with the frame, sashes and sash cord of a window, of a sash-fastening device having a channel through which the sash cord passes angularly positioned with respect to the normal position of the cord, and having engaging edges which engage the upper and lower sashes and the window frame.

5. The combination with the frame and sashes of a window, of a sash-fastening device adapted to seat on the lower sash consisting of a single tilting block seated at one corner on the lower sash and having means for engaging the frame of the window, so that when an opening movement is given to the sash said device is jammed between the sash and the window frame.

6. The combination with the frame and sashes of a window, of a sash fastening device consisting of a single tilting block adapted to be seated on the lower sash so as to tilt inwardly toward the upper sash and the window frame, and means on said device for engaging the upper sash and the window frame.

7. The combination with the frame and sashes of a window, of a sash fastening device consisting of a block, one lower corner of which is seated upon the lower sash and having means on the upper part thereof for engaging both the upper sash and the window frame.

8. The combination with the frame and sashes of a window, said frame being provided with a parting bead, of a sash-fastening device consisting of a block which seats on the lower sash and having means on the upper part thereof for engaging both the upper sash and window frame, saidblock being notched so as to extend-around the parting bead.
